Hi, I have a question on the Homework Exercise:
one of the points says:
- Create a subclass of Car class and name it as Ford. The Ford class has
the following fields and methods
- int year;
- int manufacturerDiscount;
- double getSalePrice(); // From the sale price computed from Car
class, subtract the manufacturerDiscount.
The problem that I see with this exercise is that if Ford is a sub-class of
Car, then we over0ride the method getSalePrice() in the Car class.
Since Car is the super class, this method may return 0, since it can be
overridden.
So in the Ford sub class if I code the method as follows:
public double getSalePrice(){
return super.getSalePrice() - manufacturerDiscount;
}
Then I will get a negative value for price.
Should Ford be a sub-class of Truck class?
Thanks
Raja
